Abstract

In a method for adjusting a driving force for moving a patient table of a magnetic resonance apparatus, position-relevant and/or drive-relevant patient data is provided, a minimum required driving force is determined based on the provided position-relevant and/or drive-relevant patient data, the minimum required driving force for moving the patient table is determined, and the patient table is moved with the minimum required driving force.

First claim

The invention claimed is:

1. A method for adjusting a driving force for moving a patient table of a magnetic resonance apparatus, the method comprising:
determining position-relevant and/or drive-relevant patient data;
determining, using a controller, a minimum required driving force based on the position-relevant and/or drive-relevant patient data;
adjusting, using an adjuster, the minimum required driving force to move the patient table; and
control, using the controller, a drive to move the patient table with the minimum required driving force.

2. The method as claimed in claim 1 , wherein the position-relevant and/or drive-relevant patient data comprises:
a weight of a patient;
a size of the patient; and/or
an orientation and/or positioning of the patient on the patient table.

3. The method as claimed in claim 1 , wherein the position-relevant and/or drive-relevant patient data comprises data of a patient registration.

4. The method as claimed in claim 1 , wherein determining the position-relevant and/or drive-relevant patient data comprises acquiring, using a camera and/or a sensor, the position-relevant and/or drive-relevant patient data.

5. The method as claimed in claim 1 , further comprising:
identifying, based on a movement of the patient table, a power required by the patient table; and
identifying, based on the identified power required by the patient table, an occurrence of a dangerous situation during the movement of the patient table.

6. The method as claimed in claim 5 , wherein, in response to the occurrence of a dangerous situation during the movement of the patient table, generating a warning message and providing the generated warning message to a user.

7. The method as claimed in claim 5 , wherein, in response to the occurrence of a dangerous situation during the movement of the patient table, stopping the movement of the patient table.

8. The method as claimed in claim 7 , wherein a manual confirmation input is required for the movement of the patient table to be resumed.

9. The method as claimed in claim 7 , further comprising:
determining, based on the required amount of power, an increased driving force for a resumed movement of the patient table.

10. The method as claimed in claim 1 , further comprising generating a user output and outputting the generating the user output to the user before time-critical magnetic resonance examinations.

11. A non-transitory computer-readable storage medium with an executable program stored thereon, that when executed, instructs a processor to perform the method of claim 1 .

12. A magnetic resonance apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, configure the apparatus to:
determine position-relevant and/or drive-relevant patient data;
determine a minimum required driving force based on the position-relevant and/or drive-relevant patient data;
adjust the minimum required driving force to move a patient table; and
control a drive to move the patient table with the minimum required driving force.

13. A magnetic resonance apparatus adapted to adjust a driving force for moving a patient table, the apparatus comprising:
a patient receiving area;
a scanner at least partially surrounding the patient receiving area;
a patient table configured to move a patient into the patient receiving area;
a provisioning unit configured to provide position-relevant and/or drive-relevant patient data;
a computer configured to determine a minimum required driving force based on the position-relevant and/or drive-relevant patient data;
an adjuster configured to adjust the minimum required driving force at the patient table; and
a patient table travel unit configured to move the patient table.
